This would be really horrible, and I hope it never happens. I was just readin up on CAMMᵃᵇ, and to me, CAM looks really promising. It solves the challenges with SODIMM, and the article says:
> We mentioned the faster DDR5 speeds above, but it is thought that CAMM could really take off when DDR6 arrives. Another appealing variation might be for adding LPDDR(6) memory to laptops. Traditionally LPDDR memory is soldered, so the new spring contact fitting modules might mean much better upgradability for the thinnest and lightest devices which tend to use LPDDR memory.
I'd like to see legislation passed (even if at the state/regional/provincial level) that forces laptop (and other device) manufacturers to use user-replaceable CAMM memory modules instead of solder-on modules (unless solder-on memory is absolutely needed/justified by a high technical need for it – and the bar for this should be high). Similar legislation for batteries, device screens, etc. – mandate standard interfaces and easy replacibility.
This will likely increase BOM, but it shouldn't add more than $10 to the overall average retail price of various devices.
Realistically, higher end manufacturers will just stop selling devices to that state/region/province and people who live there will figure out a way to buy what they want. There's a reason why the single most popular laptop model in the US happens to be a macbook and the iPhone is the most popular smartphone here.
There will always be laptops with DIMM slots in the future just as there are laptops that have CPU sockets today. But the bulkiness and performance gap will only increase every year. CAMM has about the same thickness as a single SODIMM slot so it only saves space if you need 2 sticks worth of RAM. Also compare 2 slot vs 4 slot DDR5 overclocks on desktop to see the impact of signal integrity.
